v7.1.5

Bug Fixes

• fix: prevent duplicate messages in real-time viewer — Race condition in 3-second polling (checkForNewMessages) allowed concurrent async calls to both add the same message. Added concurrency guard (isRefreshing) and deduplication.
• fix: add chat_id to WebSocket new_message broadcast — The payload was missing chat_id, making client-side real-time message insertion a silent no-op. Messages only appeared via polling.
• fix: deduplicate WebSocket new message handler — Added messages.some() check to prevent duplicates when both WebSocket and polling deliver the same message.
